I e-filed my 2022 tax return, and just received a letter from the IRS asking for supporting material for my 1040SR line 25d.
They ask for W2, 1042-S, 8805, 8288-A, and "other US withholding documents".
(I'm not sure why they mention 1040SR, which is the large text version of the 1040 and only applicable to paper filing for those over 65. )
My line 25d is from W2 and 1099, so the W2 makes sense, but it should have been sent to them directly from my employer.
I have no idea how I'd fill in a 1042-S or the other forms, and it seems like the IRS thinks I'm not a US Citizen (which I am.)
Any thoughts or insights on this?
